Objective To investigate the distribution of five indicators of hepatitis B(HBV-M)and its relationship with liver function parameters and HBV-DNA load in patients with chronic HBV infection in different stages.Methods The serum samples were collected from 456 patients infected with HBV.The HBV-M,liver functional parameters and HBV-DNA level were quantita-tively detected.According to the stages of disease,the patients were divided into 3 groups including chronic hepatitis B group(inclu-ding mild subgroup,moderate subgroup and severe subgroup),liver cirrhosis group(including compensatory subgroup,decompen-sated subgroup)and hepatocellular carcinoma goup.Results The ratio of HBsAg,HBeAg,HBcAb positive pattern(135 pattern) and HBsAg,HBeAb,HBcAb positive pattern(145 pattern)in the three groups were statistically different(P <0.05).In each chron-ic hepatitis B subgroup,both ALT and AST levels of 135 pattern were significantly higher than the other two patterns(P <0.05). In each liver cirrhosis subgroup and hepatocellular carcinoma group,there were statistically significant differences in ALB and TBIL levels between the three patterns(P <0.05 ).In each group,the HBV-DNA level of 135 positive pattern were significantly higher than the other two patterns(P <0.05).Conclusion With the advancement of chronic hepatitis B,there is a downtrend in the ratio of 135 pattern and increasing trend in the ratio of 145 pattern.If the stage of hepatitis B is discriminated,ALT,AST,ALB TBIL and HBV-DNA level were closely related to HBV-M pattern.

Objectives: To observe the drug seeking behavior in chronically morphine pretreated, abstinent rats and determine brain regions involved in this behavior. Methods: Preferences for morphine associated environments and Fos expression in some brain regions were measured 35 days after withdrawal of chronic morphine treatment. Results: The preference for the morphine environment was greatly increased by morphine pretreatment. The conditioned morphine pretreated group showed significantly higher Fos levels than either the conditioned or non conditioned control groups in the Cg, Ac C, BNST VL, ACE and ABL. Conclusions: A relationship between place preference behavior and neural indices of activation exist in the forebrain in response to morphine conditioned cues, which may be chronically modulated by prior morphine exposure.

The transcription activity of ectogenic human carcinoembryonic antigen (CEA) promoter in lung adenocarcinoma cells A549 was investigated for the further gene-targeting therapy. The reporter gene green fluorescent protein (GFP) driven by CEA promoter and human cytomegalovirus (CMV) promoter were relatively constructed and named plasmid pCEA-EGFP and pCMV-GFP respectively. The intensity of fluorescence was detected by fluorescence microscope and flow cytometry analysis after the pCEA-GFP and pSNAV-GFP plasmids were transfected into A549 cells through liposome respectively. The results showed (4.08+/-0.63) % of the A549 cells transfected with pCEA-AFP plasmid expressed, significantly lower than that of the A549 cells transfected with pCMV-GFP [(43.27+/-3.54) %]. It was suggested that ectogenic human CEA promoter in lung adenocarcinoma cells A549 was weakly expressed. The distinct specificity of CEA promoter in CEA high expression cells was regarded as a tool in selective gene therapy, but the transcription activity of ectogenic human CEA promoter was needed to increase in the future.

Objective: To investigate the multi-imaging diagnostic values, especially MSCT technology in patients with congenital aortic diverticulum with its clinical application. Methods: The MSCT ifndings in 12 patients with congenital aortic diverticulum were retrospectively analyzed. Results: There were 9 patients with right aortic arch and 1 with left aortic arch, all of them having coexisted aberrant subclavian artery which initially dilated like aneurysm by diverticulum changing (Kommerell diverticulum), and there was 1 patient with incomplete double aortic arch with atresia of left arch combining retro-esophageal aortic diverticulum (RAD) and 1 patient with ducts diverticulum. Echocardiogram only made the suggestive diagnosis of speeding up blood lfow or right aortic arch in 4 patients. While MSCT accurately displayed the diverticulum for the location, morphology and with or without other complications. The post-eroanterior chest radiograph indicated “double aortic node” as the special sign in 8 patients. The echocardiogram, X-ray and MSCT for correctly diagnosing the aortic diverticulum were as 0, 72.7% and 100% respectively. Conclusion: MSCT is a rather ideal non-invasive diagnosing method for aortic diverticulum, meanwhile X-ray could also make suggestive diagnosis; if MSCT and X-ray joint with echocardiogram examination may provide the effective supplement for valve structure and hemodynamics condition in relevant patients.

Objective: To explore the necessity of multi-slice CT (MSCT) and echocardiogram in diagnosing multiple cardiac myxoma or myxoma originated from special site of heart via analyzing medical imaging features. Methods: A total of 14 patients with multiple cardiac myxoma or myxoma not originated from left atrium fossa ovale were studied; the patients had operation conifrmed diagnosis in our hospital from 2003-02 to 2015-12, the imaging features of MSCT and echocardiography were analyzed and compared. Results: There were 12/14 patients diagnose by echocardiography with the accuracy of 85.7% and 11 patients diagnosed by MSCT with the accuracy of 84.6%. MSCT and echocardiography had similar pre-operative accuracy and complimentary advantages for diagnosing multiple cardiac myxoma or myxoma not originated from regular site of heart. Echocardiography was superior for examining the motion, pedicle position, shape and attachment point of cardiac myxoma; MSCT may exclude pulmonary embolism and coronary artery disease at meanwhile. Conclusion: Unconventional cardiac myxoma not only has similar image signs to typical single myxoma from left atrium, but also has the speciifc features; MSCT combining echocardiogram examinations could make more accurate diagnosis and provide a better condition for surgical treatment.
